Question

rules of writing chemical reaction

Answer 1

*In a chemical equation, the reactants are written on the left, and the products are written on the right. *The coefficients next to the symbols of entities indicate the number of moles of a substance produced or used in the chemical reaction.
*The reactants and products are separated by an arrow, usually read aloud as “yields.”*Chemical equations should contain information about the state properties of products and reactants, whether aqueous (dissolved in water — aq), solid (s), liquid (l), or gas (g).
